I don't think the repr() of a BTreeItems should show the actual items,
regardless of length.  For a typical BTree, there are probably hundreds
or thousands or more items, so repr()'ing them like an ordinary Python
sequence is madness (or "counter-productive" if you like ;-).
Furthermore, the rules shouldn't change based on size: that makes
something as simple as repr() appear random and unpredictable.

However, I would love to see
  <BTreeItems object at 0x831b208: 549 items>
instead of
  <BTreeItems object at 0x831b208>
and I bet it wouldn't be too hard either.  ;-)

Come to think of it, it would also be nice to see
  <BTree object at 0x831b208: 549 items>
